TIP.

Application filed June 22, 1925. Serial No. 88,619.

This invention relates to tips adapted to be mounted in the legs ofchairs or other articles of furniture and has for its primary object toprovide a device of this character which is strong and durable inconstruction, eflicient in operation, attractive in appearance and maybe cheaply and economically manufactured.

The many other objects and advantages of my invention will be betterunderstood by reference to the following specification when consideredin connection with the accompanying drawing, which drawing illustratescertain selected embodiments, of which Fig. 1 is a front elevation ofthe tip.

Fig. 2 is a section on line 22 of Figure 1.

Fig. 3 is a section taken on line 33 of Figure 1, and

Fig. 4 is a sectional view of a modification inserted in a sloping leg.

Referring to the drawings and particularly Figures 1 to 3 inclusive, thetip in this particular embodiment substantially consists of a circularbottom plate 10 slightly convexed. The outer edges of this plate arerolled inward, forming a retaining shoulder or flange 11 upon which thebase of the chair leg rests. Integral with the bottom plate and spacedsubstantially diametrically opposite each other are two resilientupstanding arms or lugs 1212. The upper extremities of said lugs arebent inwardly at 16 and contact at 13 so as to prevent malformation ofthe lugs when subjected to heavy compression. The socket is open at thefront and rear except for the projections 1414 which are integral withthe side members and are made to conform substantially with the innerwalls of the chair leg 17.

In actual practice, the tip is preferably made with the side membersbent slightly outward, thereby leaving a small gap between the portions1515. This is done so that when the tip is inserted into the base of thechair leg 17 or any other article in which it is to be used, the sidemembers 1212 are necessarily compressed until the portions 1515 contact.The tip is frictionally held in place due to the tendency of the metalto spring back and contact with the corresponding walls of the chair leg17,

' Referring to Figure 4, the tip is of the sloping leg type and issubstantially the same as Figures 1 and 2 except thatthe side members1-212- are disposed'at anangle to the bottom plate 10.

Since the described details are illustrative of only a single embodimentof my invention, it will be understood that the scope of same should bedetermined by reference to appended claims, said claims being construedas broadly as possible, consistent with the state of the art. v

I claim as my invention:

1. A tip of the class described, comprising a convex base plate, theouter edge of which is rolled inward to form a rim for supporting ahollow post, oppositely disposed side members projecting upwardly andconformed substantially to the outline of the inner rim of the baseplate and frictionally fitting the interior of the post, the upper endsof said members being bent inwardly and adapted to contact when themembers are pressed together.

2. A tip of the class described formed from a single sheet metal blankand comprising a bottom wall, the outer edge of which is turned inwardlyto form a shoulder for receiving the lower end of a hollow leg,oppositely disposed side members entegral with the said wall, projectingupwardly from the inner edge of said shoulder and adapted to becompressed towards each other so as to snugly fit in the leg, the upperportions of said members extending inwardly towards each other, andbeing in abutting engagement when the side members are compressed toeffect said snug fit.

3. A tip of the class described formed from a single sheet metal blankand comprising a bottom wall, the outer edge of which is turned inwardlyto form a shoulder for receiving the lower end of a hollow leg,oppositely disposed side members integral with said wall and extendingupwardly from the inner edge of said shoulder, said side members beingnormally sprung apart and adapted to be compressed towards each other tofit the inside of the leg and to frictionally engage the same,-the upperportions of said side members extending inwardly towards bers integralwith said base plate and ex-i tending upwardly from the inner edge ofsaid shoulder, the lower portions of said side M 'members beingsubstantially conformed crosswise of their lengths-to the'shape of theinside of the leg, thereby to be capable of frictionally engaging arelatively large inside surface area of the leg, and the upper endportions of said side members being of considerably narrower width thansaid lower portions, extending inwardly towards each other and being inabutting engagement when saidside members areinserted in the leg saidnarrow inwardly extending portions serving to resiliently maintain theside members in tight frictional engagement With said leg.
